The System Sensor HRL-LF is a red, wall-mount low-frequency sounder. It produces a 520 Hz tone for fire alarm notification. As a result, it meets low-frequency audible signaling requirements.
Why the System Sensor HRL-LF Uses Low Frequency
First, modern codes call for a 520 Hz signal in many sleeping areas. This low-frequency tone wakes sleeping occupants more effectively. Therefore, the HRL-LF fits hotels, dormitories, and apartments.
In addition, the sounder generates a 520 Hz ± 10% square-wave tone. It mounts on the wall for broad sound coverage. Also, a rotary switch selects tone and output settings.
Installation Features
The HRL-LF uses a plug-in design with minimal back-box intrusion. As a result, installation stays fast and foolproof. Furthermore, the low current draw eases notification circuit design.
